The detection capability depends upon the SIMS instrumental nitrogen background and the precision of the measurement.<\/p>\n<p>1.5 This test method is complementary to infrared spectroscopy, electron paramagnetic resonance, deep level transient spectroscopy, and charged particle activation analysis <b>(3)<\/b>. The infrared spectroscopy method detects nitrogen in specific vibrational states, rather than total nitrogen, and is limited to silicon with doping concentrations less than about 1 x 10<sup>17<\/sup> atoms\/cm<sup>3<\/sup>. The charged particle activation analysis detection capability is limited by an interference from boron.<\/p>\n<p>1.6 <i>This standard does not purport to address all of the safety concerns, if any, associated with its use.
